Unfortunately, as distance increases between the power supply and the device’s circuit board, so does electrical interference and noise. Regardless of the original purpose of the device, if small size or portability isn’t required for your application, it may be advantageous to replace the coin cell with an external power supply, such as a larger battery or an AC adaptor (wall wart). (Here’s a quick way to replace the coin cell with a AA on a digital tool.) The disadvantage is that they can’t hold much power and so they may require frequent changing.īecause they’re specialty batteries, the cost of replacing a small disposable cell is usually more than the cost of a much larger, higher-capacity standard battery (like a 'AA'). The advantage of the small size of these batteries (technically single “cells”) is that they don’t take up much room.

In fact, it can be used to replace batteries of all sorts of shapes and sizes.Īdditionally, if the device doesn’t include a plug for an external power supply, the power supply wires can simply be brought into the battery replacement holder along with the capacitor.Ī capacitor and copper ring soldered to a PCB to substitute for an LR44 disposable button cell.īutton or coin cells supply electricity for a wide variety of low-power portable devices, such as watches, hearing aids, LCD clocks, and digital calipers. Note that this technique can be used for purposes other than replacing a coin-size cell. This allows an external power supply to be used on small portable devices without misoperation due to electrical noise.
